The incidence of Human Papilloma Virus (HPV) in the American homosexual community is very high. This stems in part from the high number of sexual partners that some individuals in the community have. One study showed that at any point in time some 50% of sexually active homosexual men will carry HPV.
Unlike heterosexuals, where the Papilloma will usually present itself on the penis (where it will cause warts or other growths), in homosexuals the Papilloma may also be in the anus, where it will cause genital warts on the outer part of the anus as well as the inner part of the rectum.
Gay men are 17 times as likely to develop anal cancer compared to their heterosexual counterparts. Therefore, we recommend gay men be screened by a Pap smear at least once a year. The subject of HPV vaccination for homosexual men is a major discussion in many western countries today. Still, in the United States, the vaccine is supplied to gay men 26 and under.
